wvhich I declare the following to be a full,

clear, and exact description.

This invention relates to accounting machines and more particularly to machines of the type commonly known as two-motion machines, that is, machines in which keys or manipulative devices are set and the operation completed by some other in- .strumentality, such as an operating handle or lever.

The principal object of this invention is to provide an'improved form of actuators for the registering mechanism.

Another object of this invention is to provide an improved form of mechanism for ac tuating the indicators, so that they may move directly from one indicating position to another, without first returning to a normal starting position.

Another object of this invention is to provide an improved form of mechanism for recording the total, which is controlled by the resetting of the elements of the totalizer, this resetting of the totalizer elementspositioning an inking device so as to record the total in a different color from the items, so that the totals may be readily distinguished from said items.

r A further object of this invention is to provide-an improved form of [detent or latch-ing; device for holding the keys in their operated position. I A still further object of this invention is to p'rovids? an improved form of special 1ndicator, which is so constructed that when brought into position to be displayed it'conceals the amount indicators. 7

which accompany and form part of th specification.

Fig. 4; is an end elevation of the operating mechamsm, also showing thetotal key. Fig. 5 1S & rear elevation of the devices shown in Fig. 4. Fig. 6 is a detail view of one or" the gears foroperating the main driving shaft. Fig. 7 is an elevation of. the total key and cooperating mechanism. Fig. 7 1s,.a partial top plan view of the totalizer elements and resetting devices therefor. Fig. 8 is a front elevation of the indicators and the gearing therefor. Fig. 9 is a side elevation of the totalizer. Fig. 10 is a transverse sectional view throngh the machine the items and the total thereof in difierent colors.

Described in general terms the machine comprises a plurality of banks of manipulative devices, suchv as key levers,"which, when operated, directly actuate totalizerelev V ments and position type carriers for recording the items upon a record strip. Through suitable intervening mechanism the operation of the key levers also positions devices for determining the extent of movement of a set of indicators upon the operation of an oscillatory operating lever. The operation of this lever also actuates the platen mechanism to take an impression from the type. carriers, after which, through suitable mechanism driven by the operating lever, the type carriers and mechanism for actuating the totalizer elements are returned to their normal positions.

.When it is desired to record the total of the items entered upon the totalizer, a total to zero, the actuators will be moved thereby 1n the same direction as they are moved when operated by the 'key levers. This movement of the actuators will set the type carriers in position to have printed therefrom the total as represented by the totallzer elements previous to their being returned to zero position. By the operation of the oscillatory hand lever the platen will be actuated to take an impression from the type carriers, and the indicators also will beset to display the total recorded upon the record strip.- By the resetting of the totalizer elements to zero, the mechanism for inking'the type carriers will be shifted so that the total will be printed in a differ-v ent color from that of the items. A suitable locking device is provided for the-main operating lever, which is'releasedupon the operation either of one of the amount keys or of the total key. A suitable interlocking mechanism is provided between the total key and the operating keys, so as to prevent operation of the total key and.

of .one of the operating keys during the same operation of the mathine.

When desired the platenoperating mechanism may be disabled, so that the items and total thereof will not be recorded upon the record strip, but said items will, nevertheless, be entered on the totalizer elements.

A special indicator is also provided, which, when brought into indicating position, conceals the amount indicators.

Following this general description of the functions performed by the machine a more detailed description will now be given of functions.

the various parts for accomplishing these Manipulative devices 1 such as operating key levers are approximately centrally pivoted upon a transverse rod 2 which is supported by the side-frames 30f the machine.

These key levers are. arranged in groupsor banks of different denominations and near their rear ends have upwardly extending projections 4, graduated in height.

Cooperating with each bank ofke-y levers 1 is a frame 5 Which is loosely pivoted upon a rock shaft 6, the latter being suitably sup ported in the side-frames 3. The graduations 4 of each bank of key levers l'are constructed to engage with a transverse plate 7 of the frame 5 cooperating with that particular bank. When any frame 5 is rocked by the operation of one of the key levers, its plate 7 will pass into a slot 8 formed in the operated key lever and lock the'frame' and the key lever together, thereby preventing an excess or overthrow movement of the frame 5. The plate 7 passes into"the slot 8 because of the fact that the frame 5 I and the key lever describe arcs of different circles which intersect each other.

The movement of all of the key levers 1 is limited by transverse shafts 9 and 10 which are suitably supported by the sideframes 3. v

The extreme rear edges of all of the keys 1 are provided with two notches 11, in the upper ones of which normally-rest forward projections 12 of frames 13, which are loosely mounted upon the shaft 9, there being one of these frames, 13 for each group or bank of keys 1. .The hubs,of each of the frames 13 have extending ginw'ardly therefrom pins 14 which entefs a longitudinalgroove 15 formed in the shaft 9. Upon the depression of any one of the operating keys 1, the upper notch 11 will rock' the frame 13 cooperating therewith in an anti-clockwise direction, and through the pins" 14 rock the shaft 9 in a similar direction, This shaft 9 has secured thereto an arm16,'see Fig. 3, which is providedwith a laterally extending pin 1 that engages the rear edge of a locking pawl 18, which is pivotally mounted upon the shaft" 9. This pawl 18. normally engages with a lug 19 projecting from a disk 20 Which is secured to a shaft 21, which in turn is rotated by the main operating handle or lever 22, see Fig. 4, as hereinafter more fully described. From this it will be seen that upon the rocking of the shaft 9 by the depression of any one of the key levers 1, the locking pawl 18 will be withdrawn from engagement with the lug 19 and thereby will release the shaft 21 and the operating-lever 22. The locking pawl.

18 at its pivotal point is provided with'an elongated slot 23 which permits an upward movement of the pawl18 by a spring 24 tion ,as shown in Fig. 3.

Fastened to the plate 7 of each frame 5 -is.a rearwardly extending arm 25; which at its rear. end is provided with a pin 26 that plays in a slot 27 formed in a movable rack 28, which is guided in its movement by the shafts 9 and 10. These racks mesh with pinions'29 mounted upon the ends of nested sleeves 30 that surround a transverse shaft 31 suitably mounted in the side-frames 3. These sleeves at their other ends carry seg- 'ments 32, see Fig. 13, which mesh with pinions 33 secured to the ends of a second set of nested sleeves 34, see Fig. 11, which sleeves at their other ends carry type carriers 35 for recording items and the total thereof as hereinafter more fully described.

The racks 28 are provided at theirupper ends with studs 36, see Figs-1, 2 and 7, which studs project through elongated slots 37' formed in plates 38. These plates at their upper ends areforked, and the prongs of the forks are formed into rack portions 39 and 40. The rack 39 of each plate 38 normally engages with a pinion 41 which is attached to a larger pinionf4e2 which in turn meshes with a pinion 43 carried byone of the totalizer elements 44. The rack portions are provided with an elongated slot 45 through which extends a rod 46 that acts as a guide for the movement of the upper ends of the racks 38. The lower portion of each rack 38 is forked and straddles the shaft 9 which shaft acts as a guide for the lower portion of said rack plates 38. From this it will be seen that the differential movement of the frames 5 imparted thereto by the operating key levers 1, will, through the racks 28 and the actuating plates 38,

impart a similar movement to the totalizer elements 4 1.

A plurality of pawls 47, one for each rack plate 28, are loosely mounted upon a transverse rod 471, which is suitably mounted in the side frames 3. Each of these pawls 47' is forked at its upper end, the rear prong of which contacts with the rear side of one of the frames 13, while the forward prong is arranged to engage with ratchet teeth 48 .formed on the rear edge'of the companion rack plate 28. These pawls 47 are held in contact with the frames 13 by leaf springs 49, which are secured to the pawls 47 and have their free ends contacting with a transverse shaft 50, the latter being suitably mounted in the side frames 3. From this description it will be seen, that, upon the 7 beginning of operation of any one of the keys, the companion frame 13 will be rocked the down stroke of the operated key the pro-- jection 12 of' the operated frame 13'wi'll pass into the lower notch 11 of saidkey, by this movement permitting the forward prong of the pawl 4 to spring into engagement with the ratchet teeth 48 of the rack plate 28, thereby latching the plate 28 and key 1 connected thereto in their operated positions By the operation of the operating lever 22 the pawl 47 will be withdrawn,

and the key 1 and plate-28 will be positively restored to normal positions, as will appear from the descrlption hereinafter given.

, The indicators, which are of the type that are driven directly from one position to another without returning to a normal startmg position, are provided with an improved form of mechanism for accomplishing this function, which now will be described.

The upper ends of the racks 28 are connected to the forward ends of plates 51 by the studs 36, the rearward ends of said plates 51 being provided with antifriction rollers 52 which play in elongated slots 53 formed in indicator actuating racks 55. These racks at their upper ends mesh with pinions 56 secured to indicators 57 for displaying the amount represented by the keys depressed. Approximately at their centers the plates 51 are provided with triangular slots in which arod 58 plays. This rod 58 is supported by arms 59 which are fast to the rock shaft 50. This rock shaft 50 has secured thereto an arm 60, which is provided with a laterally extending pin 61 that plays in a recess 62 formed in the lower end of an arm 63, which is centrally pivoted as at 6% upon one of the side frames 3. The upper end of this arm 63 is provided with a roller 64*, which plays in a cam groove 65 formed in a disk 66 secured to the driving shaft 21. The shape of the cam groove 65 ,is such that upon each rotation of the shaft 21 the frame composed of the rod 58 and the side-arms will be oscillated an invariable eXtent first in an anti-clockwise direction and then back to normal position. From the above description it will be seen that, after the forward ends of plates 51 have been positioned by the differential movement of the racks 28 the pawls 47 will latch said racks in their adjusted n sition, so thatupon the rotation of the shaft 21 the cross rod 58 playing in the triangular slots of the plates 51 will, in its forward movement, contact with either the upper or lower walls of the triangular slots, and thereby position the rear ends of said plates, which, through the racks 55, will rotate the indicators 57.

, The racks 55 have formed on the rear edges thereof V shaped notches 67 with which the end of a locking and alining plate 68 engages, to hold the indicators in their adjusted positions. This plate 68 is secured at its lower end to a rock shaft 69 which is supported by the side frame 3. This rock shaft has extending forwardly therefrom an arm 70 to which is connected the lower end of a pitman 71, the upper end of which is forked and straddles the rotation shaft 21. Near its upper end the pitman 71 is provided with an anti-friction roller 72 which plays in a cam groove 73 formed in a disk similar to the disk 66 and which is secured to the shaft 21. Upon the beginning of the rotation of the shaft 21 the cam groove 73 will rock the plate 68 out of the notches 67 of the racks 55, so that said racks may be adjusted in order properly to position the indicators, after which the cam groove 7 3 will rock the plate 68 into the notches 67 to lock and aline the-indicators. With this style of indicators, which is moved directly from one position to another without returning to zero or normal position, there is a tendency, when the indicators are released, for the actuatingracks to return said indicators to normal position, due to the weight of said racks. When successive sales of. the same amounts are made this returning of the indicators] toward normal position would necessitate the resetting of the indicators for each sale, and in order to prevent thisunnecessary operation of the ,indicators,-the actuating racksfor the different sets of indicators, for displayin the transactions to .the front and back of the machine, are connected in such a manner that when one set of actuators are operated the other set of actuators will be moved in the opposite direction. From this 'eneral statement it will be seen that the different sets of actuators, being connected and of equal weight, and moving in opposite direc tions, will offset the tendency of either set of actuators to return the indicators connected thereto to zero or normal position. One form of mechanism for accomplishin this object isas follows.

Referring-now to Fig. 8, it will be seen that the indicators shown therein are constructed to indicate transactions in which English currency is used, but it is to be understood that the inventionis equally applicable to machines in which other monetary cators.

systems are employed. The rack which actuates the farthing indicator of the front set of indicators, meshes with a pinion 75 secured to a transverse shaft 76'. Near its other end this shaft carries a pinion 7 7 which is similar to the pinion 75 and which meshes with a broad pinion 78 loosely. mounted on atransvers shaft 79. This pinion 78 meshes with a rack 80 which in turn engages with a pinion 81 secured to the farthings indicator of the back set of indi- From this it will be seen that, through the intermediate pinion 78 the "rack '80 for the back indicator will be driven in the opposite direction, from that in which I the rack 55 is driven, and consequently the movements of the racks 55 and 80 in oppo-. site directions will ofi'set' any tendency to rotate either indicator to zero or normal position. The rack 55 for the pence indicator meshes with a pinion .82 secured to one end of a sleeve 83, loose onshaft 76, and the other end of which has secured'thereto a pinion 84 which meshes with a broadpinion 85, loose on shaft 79 and which, through one of the back set of racks 80 and pinions 81, rotates the pence indicator of the back set. The rack 55 for the units of shilling wheel meshes with a pinion 86 secured to the shaft pinions 89, 90 and 91 and the rack 80 and pinion 81. The pounds wheelis an enlarged single wheel and carries two setsof numerals thereon which are arranged in're r verse order. The rack 55 for driving this indicator also meshes with a pinion 92 loosely mounted upon the shaft 79 and,

against which abuts a coiled spring 93, so as I to offer resistance to the turning of this enlarged indicator, and thereby preventing movement of said indicator by gravity.

A no sale key 137, see Fig. 10, is mounted upon the transverse rod'2 adjacent to the amount keys 1 and near its rear end has connected ther eto the lower portion 0f a.

. is provided at both ends with hook portions,

and is normally held in the position shown in Fig. 10, with its lower end abutting a pin 144 carried by the link 138, by a spring 145, the ends of which are connected with the awl 143 and the arm 141.

. pon each operation of the machine a concealing means composed of-shields 146 carried by arms 147, which are centrally pivoted upon the rod 142, is moved to a posilink 138, the upper portion of which is protion to conceal the indicators 57 during'their adjustment, and then returned to normal position at the end of the operation of the machine so as to expose the adjusted indicators. This movement of the concealing means is accomplished by a disk 148 secured to the shaft 21 and which is provided with a cam groove 149 in which a roller 150 projecting from the forward end of a pitman 151.extends. The rearward end of the pitman 151 is connected to the vertical arm of a bell crank lever 152 'which is loosely mounted.

upon a guide rod 153. One of the arms 147 of the flash or concealing means -.is connected to the horizontal arm of the bell crank 152 by a link 154. From this it Will be seen that upon each operation of the shaft 21, the

shields 146 of the concealing means will be moved to a position-to conceal the indicators .57 and near the end of the rotation of the shaft 21 will be returned to normal position.

When the no sale key 137 is depressed the link 138 will be elevated carrying the pin 1 144 projecting therefrom away from the lower portion of the spring drawn pawl '143 so that the upper portion will contact with the rear edge of the front shield 146. Upon the rotation of the shaft 21 by the operating lever 22, the concealing means will be moved and the shield 146 will pass under the upper hook portion of the pawl 143, so that when the concealing means is returned to normal position at the end of the operation of the machine, the forward shield 146 will elevate the pawl 143 and the arm 141 to which said pawl is pivoted. This elevation of the pawl 143, will, through the lower hook portion, position additional concealing means or flashes 155 so as to conceal the front and back sets of indicators. while used to conceal the amount indicators 57, are also used as no sale indicators. In the adjustment of the no sale indicators or flashes 155 to indicating position, the forward one of the said flashes will contact with the under side of the shield 146 of the main concealing means while the lower portion of the rear no sale indicator 155 will contact with the upper part of the rear shield 146 so that upon the succeeding operation of the machine the no sale indicators or flashes 155 will be returned to their normal position by the shields 146' of the main concealing means, in which position the no sale indicator will remain until the no sale key 137, is again depressed. In the return of the no sale indicators to their normal non-indicating position the lower end of the pawl 143 will contact with the stud 144 and thereby rock the upper hook portion of said pawl out of engagement with the front flash 146 so that the said flash or shield may, be returned to its normal non-concealing position independently of said pawl. Astud 156 projects from the arm 141 and normally contacts with the forward edge of the link 138 so as to limit the downward movement of the arm 141. The no sale key has cooperating therewith one of the latching which are connected to frames 13 similarly to the amount keys, which latching frame is provided with a stud 14 which projects into the longitudinal groove 15 of the shaft 9, so that by the operation of the no sale key the shaft 9 will be rocked to release the main operating mechanism of the machine in the same manner as if one of the amount keys were operated.

It might be here mentioned that the width of the longitudinal slot 15 formed in the shaft 9 is greater than the thickness of the studs 14 which project from the frame 13, thus permitting anyone of the frames 13 to rockthe shaft 9 independently of any of the other frames. This shaft is returned to its normal position by a spring 157, the ends of j w the saidshaft and to. one of the side frames 3.

The main operating lever 22, see Figs 4 These flashes 155,,

similar pinion 98 are fast on a sleeve 99 and the pinion 98 in turn meshes with a gear 100 which is mounted loosely upon'the shaft 21 adjacent to the gear 95. The gears 95 and 100 are provided with spring pressed pawls 101 and 102 respectively which are arranged to engage with a longitudinal groove 103 formed in the shaft 21 and drive said shaft as the gears are rotated.

As the operating lever 22 is moved forward in an anti-clockwise direction the segment 94 will, through the pinions 96 and 98,

rotate the gear 100 in a similar direction and through the pawl 102 carried by said gear 100 rotate the shaft also in an anticlockwise direction. The segmcnt 94 meshing with the gear 95 directly will drive said gear in clockwise direction so that the pawl 101- will have no effect upon the shaft 21' during the forward movement of the op erating lever 22. This forward movement of the operating lever 22 will rotate the shaft 21'and the gear 95 a half rotation in opposite directions, so that the pawl 101 Will engage With..the longitudinal slot 103 at the end of the forward movement of the operating lever 22. Upon the return movement of the lever22 the pawl 101 will now pick up the shaft 21 and complete the rotation thereof while the gear 100 carrying the pawl 102 will rotate idly back to normal position. It will be seen that by this construction the oscillatory movement of the operating lever 22 is converted into a rotary movement of the shaft 21.

A printing mechanism.forms a part of this invention, and said mechanism is constructed to record upon a record strip items entered in the machine and the total thereof, the items and the total being recorded in different colors, so that they may be readily distinguished from each other.. A description of the preferable form of mechanism for accomplishing these functions now will be given.

The shaft 21, at the opposite end from that upon which the gears 95 and 100 are mounted, has attached thereto a disk 104 (Fig. 12), which is provided with a cam groove 105 in which plays an anti-friction roller 106 projecting" from-one endof a pitman 107, the-other end of said pitman, being connected to alink 108 which is pivotally mounted upon a stud 109 projecting from one of the frames 3'.of the printing 111,1 formed in one end of an arm 112 that is loosely mounted upon a stud 113 projecting from the printer frame. This arm 112 is connected through a hub 114 to a forwardly extending arm 115 which carries a plate 116 that in turn carries the record strip 117 and a platen 118. The arm 115 is provided with notches or recesses 119 and 120 into which project studs 121 and 122 extending from the plate 116 and by this means the said plate 116 is supported upon the arm 115.' An adjusting screw 123 extends through the plate 116 into contact with the forward end ofthe arm 115 so as to adjust the surface of the impression platen 118 relative to the type carriers 35.

The record strip 117 is fed from a' supply roll 12%, mounted upon the plate 116, over the platen 118 and thence to a storage roll 125 also mounted upon the plate 116. From this it will be seen that upon the rotation of the shaft 21 in the direction of the arrow the pitman 107 will be reciprocated, and,

through the stud or roller 110, rock the arms 112 and 115 so as to carry the platen 118 into contact with the type carriers to take-fan impression upon the record strip T he storage roll 125 for the record stripis'provided with a ratchet wheel 126 with which a feed pawl 127, pivotally mounted on one ofthe printer frames 3' of the machine engages, and is held in engagement with said ratchet 126 by a spring 128. When the platen 118 is elevated to take an impression from the type wheels 35, as pre viously described, the ratchet 126 will also move upwardly, which movement will carry the next rearward tooth of the ratchet into engagement with the forward end of the feed pawl 127, so that-as the frame 116 carrying the platen '118'a'nd the ratchet 126 is returned to normal position, the said ratchet and storage roll 125 will be advanced one tooth. A retaining pawl 129, carried bythe plate 116, engages and ,holds said ratchet 126 and preventsfretrograde movement thereof; A forward extension 130 of the arm 112 contacts with a stud 131 projecting from the printer frame, and thereby limits the clockwise movement of .the arms 112 and 115. e The plate 116' carrying the platen 118 and the supplyand the storage rolls'124 and 125 may be detached from the arm115 by raising the rear end of said plate, so that the I stud 121 will pass out of the notchor'rece'ss 119, during which movement the stud 122 until the stud or roller 122 passes out of the notch or recess 120 formed in the rear end of arm 11'5.

The link 108 is adjustable relative to the as stud 109 so that the platen operating mechaesaas ters for indicating whether the platen mechanism is disabled or enabled. An enlarged slot132 is formed in the lower end of the link 108 and is provided with offsets 133, the upper of which engages with the stud 109 when the platen operating mechanism is enabled and the lower of which is arranged to engage with the stud 109 when the said platen is disabled. The link 108 is provided wit a disk 134 which is mounted on the insi e of "the frame 3' and also with a knob 135 which projects through an opening 136 formed in the said'frame. This disk 134 is provided with the charactersfOn and Oif, which are arranged to be displayed singly through the opening 136 to indicate the condition of the platen mechanism, and as shown in Fig. 12, the platen operating mechanism is in operative condition. When it is desired to disable the platen mechanism, the operator grasps the knob 135 and.

moves the lower end of the link 108 forward slightly, and then elevates said link until the lower offset 133 of the slot 132 engages with the stud 109 projecting from the frame 3. This elevation of the link 108 carries the roller 110 out of the'recess 111, so that when the pitman 107 is reciprocated it will not operate. the arm 112 of the' platen mechanism, and consequently no impression will be taken fronrthe type carrier 35. When the link 108 is in this position the character fOfl will appear through the opening 136 which, when said arm is rocked by the'cam 158, passes into engagement with the teeth of the pinions 33 and thereby alines the type carriers 35, so that a perfect impression may .be taken from. said type carriers.

An ink ribbon forming a part of the printing mechanism now will 'bedescribed. This ribbon is employed to ink the type carriers and. is fed, by operations of'the machine,

from one spool to another, and the feed automatically reversed when said ribbon is nearly unwound from either ofsaid spools.

A frame 162 composed of rightangle plates 163and 164, see Figs. 11 and 14, is secured .to the left-hand sideframe 3 by studs 165 which project through elongated slots 166 formed in the plate 163 ,of said frame, Sleeves 167 are mounted upon suitable studs projecting from the plate 164 and said sleeves carry spools 168 attached'to which are the ends of an inking ribbon 169. This ribbon is led from one of the spools beneath the type carriers 35, see Fig. 11. then around a stud 170 extending from an arm 171 forming a part of the frame 162 and thence back to the other spool. Slidably mounted upon the sleeves 167 is a plate 172 which is connected by a pin .173 to the lower end of a plate 174 which is suitably guided upon a supporting frame 175 for the type carriers. This plate 174 at its upper end is ,bent at right angles and straddles the driving shaft 21. Projecting from the .upper end of the plate 174 is a pin 1755 which plays in a cam groove 176 formed in a disk 177 secured to the shaft 21. The shape of the groove 176 is such that it reciprocates the plate 174, and through the pm 173, the plate 172. Centrally pivoted upon the plate 172 is a pawl 178, see Fig. 11, the ends of which are arranged alternately to engage with ratchet wheels 179 secured to the sleeves 167. This pawl 178- is held frictionally in position to engage either of the ratchets 179 by a re taining paw]. 180, which is pivotally mounted upon the plate 172 and is held into engagement with either side of a V shaped 'projection of pawl 178 by a spring 181. At

its centerthe pawl 178 has projecting rearwardly therefrom a pin 182, which is in the path of aipin 183 projecting from a worm gear 184, the latter meshing with a worm 185 secured to the upper sleeve 167, carrying the upper ribbon spool 168 and the upper ratchet 179. It will be seen from this description that the worm gear 184 is slightly moved upon each operation of the machine, and that after a certain number of operations the pin 183, carried by said worm gear,

will contact with either the upper or lower side of the pin 182 projecting from the feed pawl 178, so as to rocksaid pawl about its pivotal point, whereby the disengaged portion of the pawl will engage with its ratchet 179, and upon succeeding operations of the machine feed the ribbon in a reverse direction, this pawl 178 being frictionally held in its adjusted position by the retaining pawl 180. A double pointed retaining pawl 186 slidably mounted upon the plate 164 is held in engagement with the ratchets -179 by a spring 187 so as to prevent accidental displacement of the ribbon spools.

After an impression has been taken from the type carriers by the platen, a pin 188..

see Fig. 2, projecting from a'disk 189, secured to the shaft 21, will contact with the forward prong of a V shaped plate 190' which is rigidly secured to the shaft 9 and rock said shaft in an anti-clockwise direction,

which movement will, through one 'of the side walls of the longitudinal slot formed in said shaft contacting withthe studs 14, rock the'latch frames 13, and therebywithdraw the projections 12 of said frames from the notches 11 of the keys 1. This of the frames 13 will rock the pawls 47 also, against the tension of the leaf spring 49, and thereby Withdraw the ends of said pawls out of engagement with the ratchet teeth 48 formed in the rear edge of the rack plates 28.

Immediately after the withdrawal of the pawls 47 from engagement with the ratchet teeth 48 of the plates 28 the shaft 6 will be rocked in a clockwise direction by a cam 191, see Fig. 2, secured to the shaft 21, which disk will move forwardly a pitman 192 the forward end of said pitman being secured to an arm 193 which is fast to the rock shaft 6. This rocking of the shaft 6, will, through pins 194, see Fig 1, carried by said shaft and engaging with the walls of recesses 195 formed in the hubs of the frames 5, which are pivoted upon said shaft, positively restorethe previously adjusted frames to normal position, and, through the pins 26 playing in the slots 27 ofthe racks 28, restore said racks to normal position.

Previous to the restoration of the differentially movable frames 5 and the racks 28 to normal positions, the actuating plates 38 mounted upon the racks 28 will be shifted to an intermediate position so that the pinions 41 will be between the rack portions 39 and '40 of the actuating plates 38, whereby the. return movements of the actuating plates 38 with the differentially movable frames 5 and the rack plates-28, will have no effect upon the totalizer elements 44. This shifting of the actuating plates 38 to intermediate positions is accomplished by a cam disk 196, see Fig. 7, secured to the driving shaft 21, which disk shortly after the beginning of the rotation of said shaft, will draw rear wardly a pitman 197 having its extreme forward end connected to the lower end of an arm 198, the upper end of which is secured to a total key 199. One end of the rod 46, which acts as a guide for the actuating lates 38, projects intoa recess 200 formed in the arm 198, so that when the lower end of the said arm 198 is moved rearwardly as just described, the rod 46 will also be moved rearwardly. This rod is supported by vertical arms 201, which are fast at their lower ends to a shaft 202, suitably mounted in the side frames of the machine. Near the end of the rotation of the shaft 21, the pitman 197 will be moved forwardly and thereby shiftthe actuating plates back to 28 owing to the elongated slots 37 which are formed in said plates, and through which the studs 36 pass.

. It will be recalled that the shaft 9 is-rock ed movement is independent of the rack plates uponthe operation ofeither the amount keys 1 or the no sale key 137, and a hook portion 262, see Fig. 2,. ofthe V shaped plate 190 secured to said shaft 9 will in either case pass into the path of a shoulder 263 formed upon the disk 189, and thereby prevent the rotation of the shaft 21 until the key is fully depressed, when the forward projection 12 of the latching frame 13 willenter the lower notch 11 of the operated key. This will permit the shaft 9 to return to its normal pos1- tion by its spring 157, see Fig. 10, thereby unlocking the shaft 21, so that the same may I be rotated by the operation of the lever22.

One portion of the disk 189 is reduced in radius so that when the pin 188, pro ecting from said disk, contacts with the forward arm of the V shaped plate 190 during the rotation of the shaft, the hook portion 262 of i said plate will not bind against the periphfrom the pawls 47 by the return stroke of the operating lever 22.

Mechanism is prov1 total, and this mechanism is controlled by th totalizer elements, so that in order to record the total it is necessary to reset the totaliz'er elements to zero, and this resetting of the totalizer elements will advance the type carriers through the 'distance the said totalizer elements are reset. When it is desired to record a total, the total key 199, see

Figs. 4 and 7, wnich is mounted'upon shaft 204, which supports the pinions 41 and 42, and upon a stud 205, is pushed rearwardly, which rearward movement will also carry the upper end of the arm 198 rearwardly,

' and, through the guide shaft 46 projecting into said arm, will carry the forward rack portions 40 of the actuating plates 38 into engagement with the pinions 41. Now, when the totalizer elements 4-4 are rotated in the reverse direction from that inwhich they are driven by the rack plates 39, they will, through the pinions43, 42 and 41, elevate the actuating plates 38 in the same manner as when said plates are operated by the amount keys 1. This movement of the actuating plates will, through the racks 28 to which said plates are connected, rotate the type carriers 35 through the pinions and nested sleeves connected tosaid racks, as

previously described. It is to be understood that'there are other racks 28 and actuating plates 38 than those ded for recording the directly operated by the amount keys 1, which additional racks and actuating plates are for the purpose of setting type carriers 35 under the control of the higher denominational elements 44 of the totalizer, which are not operated directly upon the operation of the amount keys, but receive their movement through the transfer devices shown in Fig. 9 and hereafter described. After the recording of the total, which takes place upon the operation of the operating lever 22,

the items, these additional actuating plates 38 and racks 28 are restored to their normal positions by fingers 265, see Fig. 2, which contact with pins 266 projecting from the additional actuating plates 38. These fingers 265 project rearwardly from a sleeve 267 that isloosely mountedupon the'shaft 202, and extending upwardly from thissleeve is an arm 268, to which is connected the rear end of a link 269, the forward end of said link being connected to anarm 27 0 secured to the rock shaft 6. From'this it will be seen that the additional racks 28 and the plates 38, which are. used only in the recording of totals and with which no differentially movable plates '5 cotiperate, are positively returned to their normalpositions through devices slightly differentfrom those which return such of the racks 28 and actuating plates 38 as are directly operated by the amount keys 1, but the return of all said plates occurs thrqugh the same instrumentality, namely, the rock shaft 6. This in a manner similar to the recording of inward movement of thetotal key 199 will rock the shaft 202 bearing the arms 201 which support the guide rod 46 so that an arm 206, see Fig. 3, extending from said shaft 202 will, through a. pin 207 extending from the arm 206, rock the latch pawl 18 from engagement with the stud 19-by contacting with a forward projection of said latch pawl, and thereby release the driving shaft 21 and the operating lever 22 for actuating said shaft. By the operation of the lever 22, the shaft 21 will be rotated and a cam portion1 196, formed in the disk 196 carried by'the' shaft 21, will engage with a roller 208 projecting from the total key and return said key toits outer position, which movement will ordinarily return the actuating plates 38 to their normal position, as

shown inthe figures of the drawings, but

simultaneously with the outward movement of the total key 199 the pitman 197 'will be drawn rearwardly, which movement will counter-act a portion of the outward movement of the actuating plates 38 so that said plates will be held in an intermediate position to permit the return of said actuating plates by'the return movement of the differentially mov'ableframes 5, as heretofore described.

The totalizer elements 44 are loosely seen that it is impossible to reset the totalizer elements without connecting the actuators 38 to said elements and through said actuators adjusting the type carriers into position for printing the total. This total key 199 is latched in its operated position by a pawl 214 which is secured to a shaft 215. This shaft has extending rearwardly therefrom, see Fig. 7, an arm 216, having a pin 217 which projects into a cam groove 218 of a disk which is secured to the driving shaft 21. Upon the first movement of the shaft 21 the cam groove 218 will rock the shaft 215, so as to release the pawl 214 from engagement with the projection of the total key, whereupon said total key may be I .returned to its outermost position.

a As previously mentioned, the totalizer wheels are rotatedin an opposite direction when they are being reset to zero from that in which they are rotated when being actuated by the rack plates 38, and 111 order to reset these totalizer wheels or elements 44 to zero positions they are provided with pro jections 219, see Fig. 7 with which projections 220 extending from collars 221 are arranged to engage and rotate said wheels in a. reverse directlon.

The projections 220 of the collars 221 are'normally out of the planes of movement of the projections 219 of the totalize'r elements 44, so that the said totalizer elements may be repeatedly rotated without contacting with the projections 220 of the collars 221. Upon the rotation of theshaft 209 supporting the totalizer elements 44, the projections 220 will be moved into theplanes of movement of the projections & 219 by a pin 222 fast to and projecting from shaft 209 and which normally stands in a camming recess 223 of a boss 224 on the right hand side frame 3. The continued rotat on of the shaft 209 by the knurled knob 210, will bring the projections 220 into contact with the projections 219, and carry said wheels back to normal or zero position. Near the end of rotation of the shaft 209, a pin 209 projecting from the shaft will engage with a camming portion of a plate 210, Fig. 7, secured to the left hand side frame 3 and positively restore the shaft 209 to its normal position, The shaft will be arrested at the end of its rotation by a pin 225, see Figs.

4 and 7, extending laterally from the disk 211 secured to the shaft, which will engage with a hook portion formed at the forward end of a pawl 226 which is pivoted upon a transverseeshaft 227. The pawl 226 1s released from engagement with the pin 225, upon the beginning of rotation of the shaft 21, by a pin 228 projecting from an arm 229 securedto the rock shaft 215. Upon the beginning of rotation of the said shaft 21 the cam groove 218, see Fig. 7, will rock the shaft 215, and through the pin 228 engaging with the underside of the pawl 226. elevate the forward end of said pawl, which pawl will immediately be drawn rearwardly by a spring 230, the ends of which are secured to the pawl and to the side frame. This longitudinal movement of the pawl 226 is permitted by an elongated slot 231 through which the shaft 227 passes. As previously mentioned the items and the total are printed in difierent colors so that they may be readily distinguished from each other, and the bicolor ink ribbon used for this purpose is shifted in the following manner. Upon the rotation of the shaft 209, as just described, a cam disk 247 fast thereon, see Fig. 14, will engage with a' roller 248 projecting from" the center prong 249 of a lever 250, which is pivotally mounted as at 251 upon the left hand side frame of the machine, and rock said lever. in a'clockwise direction. movement of the lever will carry a hooked end of a prong 252 of said lever, into position to intercept the movement of a pin 253 carried by the cam disk 247, and thereby aid the pin 225 and pawl 226 inarresting the shaft at its normal or zero position. This clockwise movement of the lever 250 will carry a roller 254, projecting from another This prong of said lever, into the path of a camming projection 255 of the disk 177, which pro ection, at the end of the rotation of the shaft 21, will engage with the roller 254 and restore the lever 250 to its normal position as shown in Fig. 14. This lever 250 is further provided with a downwardly extending arm 256, which at its extreme lowereend is forked and straddles a pin 257, projecting from the plate 163 of the frame" 162 carryingnthe inking ribbon 169. It will be seen thatas lever 250 is rocked in a clockwise di rection, as ust described,the forked end of the arm 256 of said lever will carry-the frame I 162 rearwardly upon the studs 165, which .support said frame upon the side frame of the machine. The plate 163 for the frame 162 has projectingitherefrom a roller 258,

which' is arranged to pass .into V-shape'd notches 259 formed on the underside of a pawl 260, whichis pivoted to one of the studs 165 which support the frame 162. This pawl is drawn into contact with the roller 258 by a spring 261, the ends of which are attached to the free ends of the pawls 260 and to the forward stud 165. This pawl 260 and the stud 258 are arranged to hold the frame' 162 carrying the inking ribbon 169 in its ad j'usted position and to prevent accidental disbe noted that the frame 162 carrying the ribbon 169 is not returned to its normal position by the projection 255 engaging the roller 254 until the very end of the operation of the machine, while the impression is taken from the type carriers at the end of the first half rotation of the main operating shaft 21, as fully shown in Fig. 12.

In order to prevent manipulation of the totalizer elements 44 it is desirable at all times to have said elements under the contr'ol of either the actuators 38 or the transferdevices. Normally the actuators 38 are in engagement with the totalizer elements while-the transfer devices are disengaged therefrom. In ordinary operations ofthe machine where items are accumulated upon the totalizer the transfer devices are engaged with the totalizer elements previous to the disengagement of the actuators 38 by the followin mechanism.

Referring now to Fig. 7 it will be seen that the cam groove 218, in which rests the roller 217 of the arm 216, is so shaped that upon the beginning of rotation of shaft 21 in the direction of the arrow shown in said figure the arm 216 will be rocked in an anticlockwise direction and also the shaft 215 to which the arm 216 is secured. This shaft is provided with upwardly extending arms- 275, Fig. 9, one for each transfer device or element 264, and each arm at its upper end is provided with a pin 276 that extends into an elongated slot 277 of its companion transfer device 264. From this it will be seen that upon the rocking of the shaft 215 the tran fer devices 264, which are slidably mounted upon the shaft 227, will be moved into engagement with the pinions 43 of the totalizer elements 44. The purpose of the elongated slots 277 in the transfer devices 264 is to permit movement of said devices in effecting the transfer independent of the arms 275. The cam groove 218 will hold the transfer devices 264 in engagement with the totalizer elements until near the end of the operation of the machine.

. After the engagement of the transfer devices with the totalizer elements by the cam groove 218, the actuators 38 will be moved to an intermediate position by the cam disk 196, in which position the actuators are disengaged from the totalizer elements. While in this intermediate position the actuators will be returned to their normal positions as previously described, and then reengaged with the totalizer elements previous to the disengagement of the transfer devices from said totalizer elements. This intermediate position of the actuators occurs also upon the operation of thetotal key preparatory to'the recording of the total. It will be recalled that upon the operation of the total key 199 the actuators 38' will be rocked or shifted so as to bring the forward rack portions 40 of'said actuators into engagement with pinions 41 and disengage the portions 39 therefrom. During this shifting of the actuators there occurs a time when neither rack portion of the actuators is in engagement with the pinions 41, this inter-- mediate position being necessary to permit the restoration of the actuators independently of the totalizer elements. By holding the total key with the actuators in their intermediate position it would be possible to manipulate the totalizer elements if access I were gained thereto but this is overcome by engaging the transferdevices with said ele ments during this period, which is accomplished in the following manner. Upon the 275 and pins 276, Fig. 9, carried thereby move the transfer devices 264 into engagement with the totalizer elements. After the total key is fully depressed, by which time the portions 40 of the actuators will be in engagement with the pinions 41, the shaft 215 will be returned to normal position by a spring 278, which is coiled about the shaft and has one end secured thereto while the other end is coiled about the shaft 204. This return of the shaft will withdraw the trans-- fer devices 264 from engagement with the totalizer elements.

The transfer devices above described are substantially identical with those shown and described in a copending. application of the present inventor which was filed Feb. 5, 1907, and numbered 355,924.- This particular transfer mechanism forms no part of the present invention except in combination with the elements of this invention and it is thought no definite description need be given'thereof.

Means will now be described for preventing the operation of both one of the key levers 1 or 137 and the total key 199 during a single operation of the machine. This is essential as otherwise the machine would be open to manipulation. When an amount key or the No Sale key 137 is operated the straddle the shaft 6. Upon the beginning of the movement of the shaft 6the cam slot 233 will elevate the plate 235 through its pin 234, so that the upper end of said plate 235 will pass in the rear of a stud 236, which projects through a slot 237 formed in the right hand side frame 3. This lug 236 projects from the vertical arm 238 of a bell crank lever and is straddled by a portion of the total key 199.' A pin 239 projecting from the side frame 3 engages with the rear edge of the plate 235, so as to prevent rotary movement of the plate 235 about the shaft 6 in a clockwise direction. This plate is held in engagement with the pin 239 by a spring 240, the ends of which are fastened to the plate 235 and the side frame 3. From this it will be seen that when either one of the amount keys 1 or the No Sale key 137 is operated, the plate 235 will be elevated" and pass to the rear of the stud 236 and thereby lock the total key 199 from operation. When the total key 199 is operated first, the bell crank carrying the stud 236 will be retated in a clockwise direction about the shaft 202 and the horizontal arm 241 of the previously mentioned bell crank, which carries the stud 236, will pass in front of an arm 242 extending upwardly from the shaft 9 and remain in front of said arm 242 until the total key 199 is restored to normal position, as previously described. As the shaft I 9 carrying the arm 242 is rocked when either one of the amount keys 1 or the No Sale key 137 is operated, it will be seen that it is impossible to rock said shaft when the total key is depressed, and consequently the keys 1 and 137 are prevented from being op erated. When the total key is depressed and the total elements 44 are reset to zero, the

. differentially movable frames 5 will be elevated, as previously described, and consequently the shaft 6 will be rocked. This rocking of the shaft 6 will elevate the plate 235 by the cam slot 233 operating upon the roller 234 carried by the plate 235. This plate 235 in its upward movement, when the total key 199 is depressed, will pass in front of the stud 236 and when the total key 199 and the bell crank carrying the stud 236 is returned to normal position upon the beginning of the rotation of the shaft 21, as previously described. the stud will contact with the rear edge of the plate 235 and carry the upper, end of said plate forwardly about the shaft 6 against the tension of the spring 240, after which the said plate 235 will be cammed downwardly out of contact with the stud 236 upon the return of the shaft 6 by the plate 232 carried by said shaft, after which the plate 235 will be returned to its normal position in contact with the stud 239 by the spring 240.

The shaft 50, see Fig. 2, has a rearwardly and downwardly extending arm 243 which carries a flip pawl 244. This flip pawl is arranged to engage and depress the forward end ofa centrally pivoted lever 245 as the shaft 50 is returned toward normal position, and thereby elevate a drawer plunger 246 which is secured to the rear end of the lever 245. The lower end of this plunger is arranged to engage and hold a cash drawer, not shown, in an inaccessible position when said plunger is in its normal position, and when the said plunger is elevated the drawer is arranged to be propelled forwardly by any suitable form of spring as is well'understood in the art.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described as it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
